Blood pressure, heart rate, baroreflex sensitivity and cardiovascular autonomic modulation of normotensive and hypertensive groups.

Va1ues are mean ± SD.W = Wistar; SAD = sinoaortic denervation; SHR = spontaneously hypertensive rats; SHRSAD = spontaneously hypertensive rats with sinoaortic denervation.HR = heart rate; PI = pulse interval; SD PI = standard deviation of pulse interval; SBP = systolic blood pressure; SD SBP = standard deviation of systolic blood pressure; PIV = pulse interval variance; LF (ms2) = low-frequency band of heart rate variability; HF (ms2) = high-frequency band of heart rate variability; LF band (%) = low-frequency band of heart rate variability; HF band (%) = high-frequency band of heart rate variability; SBPV = SBP variability; LF SBP (mmHg2) = low frequency band of SBPV; BRI = bradycardic response index; TRI = tachycardic response index;apbpcp
